Optimising Your Skincare Routine with Active Ingredients: A Deep Dive

Skincare products with active ingredients like antioxidants, retinol, Vitamin C, and acids have become increasingly popular for their powerful, transformative effects. But navigating these ingredients requires understanding their benefits, proper application, and how to safely incorporate them into a routine. Here’s a guide to help you get the most out of these potent skin care ingredients.

Antioxidants

Antioxidants are compounds that combat free radicals—unstable molecules that damage cells and accelerate ageing. By neutralising free radicals, antioxidants help protect the skin from environmental stressors, such as pollution and UV radiation, which can cause premature aging, dullness, and hyperpigmentation.

1. • Popular Antioxidants in Skincare:

     • Vitamin C: A powerful antioxidant that brightens skin, reduces the appearance of hyperpigmentation, and boosts collagen production.
     • Vitamin E: Often paired with vitamin C, this antioxidant has soothing, anti-inflammatory properties and enhances the skin's moisture barrier.
     • Niacinamide: A form of Vitamin B3 that reduces inflammation, improves skin elasticity, and minimises the appearance of pores.
     • Resveratrol: Derived from grapes, this antioxidant offers anti-aging benefits and is great for calming sensitive skin.

   • How to Use Antioxidants:

     • Application: Most antioxidants can be used both morning and evening. However, vitamin C is often recommended for daytime use as it protects against UV-induced damage.
     • Pairing: Antioxidants can be layered with other ingredients. Vitamin C pairs well with Vitamin E and ferulic acid, creating a potent, synergistic effect.
     • Storage: Certain antioxidants, like Vitamin C, can degrade when exposed to light or air. Look for opaque or dark bottles, and store them away from heat.

       Retinol (Vitamin A Derivatives)

       Retinol is a gold-standard ingredient for anti-aging and skin renewal. It boosts cell turnover, which can reduce fine lines, wrinkles, hyperpigmentation, and acne. It is also known to stimulate collagen production, making skin appear firmer and smoother over time.

       • Types of Retinoids:

         • Retinol: The most common, over-the-counter form of vitamin A that is effective but less potent than prescription-strength retinoids.
         • Retinoic Acid (Tretinoin): A prescription-strength retinoid that works more quickly than retinol but can cause irritation.
         • Retinaldehyde: A gentler alternative to retinoic acid that requires fewer conversion steps in the skin than retinol, offering faster results with less irritation.

       • How to Use Retinol:

         • Start Slowly: Start with a low concentration (0.25% or lower) if you’re new to retinol. Use it 1-2 times a week, gradually increasing frequency as your skin adapts.
         • Application Tips: Apply at night, as retinol can make the skin more sensitive to sunlight. Follow with a moisturiser to minimise potential irritation.
         • Avoid Combining with Other Actives: Avoid layering retinol with strong exfoliants (like AHAs and BHAs) as this can lead to over-exfoliation and irritation.

2. Vitamin C

   Vitamin C, also known as ascorbic acid, is a multi-functional antioxidant that brightens skin, reduces hyperpigmentation, and aids in collagen synthesis. It's a key ingredient for those looking to combat signs of ageing, improve skin radiance, and protect against environmental damage.

   • Forms of Vitamin C:

     • L-Ascorbic Acid: The most potent and effective form, but also the most prone to oxidation.
     • Sodium Ascorbyl Phosphate & Magnesium Ascorbyl Phosphate: These are stable, gentler derivatives that may be better suited for sensitive skin.
     • Ascorbyl Glucoside: A stable form often found in water-based serums, making it easy to layer with other products.

   • How to Use Vitamin C:

     • Application: Typically applied in the morning, as it helps protect the skin from UV damage when used under sunscreen.
     • Pairing: Works well with vitamin E and ferulic acid, which stabilise and enhance its antioxidant effects.
     • Consider pH: L-ascorbic acid requires a low pH to be effective. Be cautious when layering with products like niacinamide or peptides, as they may not be compatible with a low pH environment.

3. Acids (AHAs, BHAs, and PHAs)

   Acids in skincare are primarily used for exfoliation, removing dead skin cells, unclogging pores, and improving texture. Different types of acids target different skin concerns, making them versatile and highly customizable.

   • Types of Acids:

     • Alpha Hydroxy Acids (AHAs): Water-soluble acids, such as glycolic and lactic acid, that exfoliate the skin's surface, improving texture and brightness.
     • Beta Hydroxy Acids (BHAs): Oil-soluble acids, like salicylic acid, which penetrate deeper into the pores, making them ideal for oily or acne-prone skin.
     • Polyhydroxy Acids (PHAs): Larger molecules that exfoliate the skin’s surface more gently, making them suitable for sensitive skin.

   • How to Use Acids:

     • Frequency: Start with a low concentration 1-2 times per week, especially if you are new to acids. Gradually increase as tolerated.
     • Layering: Avoid using multiple strong acids in one routine. For example, using both AHAs and BHAs together can lead to over-exfoliation and sensitivity.
     • Sun Protection: Acids can make the skin more susceptible to UV damage, so it’s essential to follow with SPF during the day.

General Guidelines for Incorporating Actives

1. Patch Test First: Especially if you have sensitive or reactive skin, always do a patch test before introducing a new active ingredient.
2. Gradual Introduction: Start with one active at a time and use it consistently for a few weeks before adding another. This allows your skin to adjust and lets you identify if any specific ingredient causes irritation.
3. Simplicity is Key: It can be tempting to layer many actives at once, but often, less is more. Overloading the skin with actives can lead to irritation, dryness, and inflammation.
4. Sun Protection: Sunscreen is non-negotiable when using active ingredients, particularly in the daytime. UV rays can exacerbate irritation and reverse the positive effects of these ingredients, leading to faster ageing.
5. Listen to Your Skin: Active ingredients are powerful, but they can also be irritating if overused. If your skin feels dry, sensitive, or starts to flake, consider reducing the frequency or strength of the actives in your routine.
